The very best blades, Valyrian Blades, are relics of Old Valyria. They are exquisite weapons, crafted using forgotten enchantments to produce the very best quality weapons. Nothing holds quite the edge like Valyrian steel. Only a handful of such swords still exist to this day.

One of the two Valyrian steel blades belonging to House Targaryen. This sword was wielded by Aegon I during the wars of conquest. It was passed down to the heirs apparent throughout the years until Aegon IV (The Unworthy) gave the sword to his bastard son Daemon after he had demonstrated great prowess in battle. This was seen by many to be Aegon's recognition of Daemon as his son and his intention for Daemon to succeed him instead of his trueborn heir Daeron. This matter was further complicated by Aegon IV legitimizing all his bastards on his death bed. Daemon took the name Blackfyre as his surname and led the Blackfyre Rebellion against House Targaryen. The sword has since been lost.

The ancestral Valyrian Greatsword of House Lannister. It was lost when Tommen II, King of the Rock, sailed to Valyria and failed to return. As such House Lannister has been without a Valyrian steel blade for centuries, much to the chagrin of Tywin Lannister the current patriarch. Tywin Lannister has tried to purchase swords from minor houses, but these poor houses are loathe to part with their heirlooms.

The second of the two Valyrian steel blades owned by House Targaryen. It was wielded by Visenya, sister wife to Aegon I. The sword was also wielded by the famed Prince Aemon the Dragonknight. The last known owner of the sword was one of Aegon IV's great bastards, Brynden Rivers (a/k/a Bloodraven and a/k/a the Three-Eyed Raven). The sword's whereabouts are unknown.

The Valyrian blade of House Mormont, this blade has served as the sole source of wealth for an otherwise impoverished house. Left behind after Ser Jorah Mormont's disgrace and subsequent fleeing of Westeros. The blade was later given to Jon Snow by Lord Commander Jeor Mormont after Jon saved him from a wight attack.

Described as a hand and a half or bastard sword. Originally had a pommel in the likeness of a bear's head, it was refashioned into a wolf's head after being damaged by fire in the wight attack on the Lord Commander.

Oathkeeper is a Valyrian steel longsword which was forged from Eddard Stark's greatsword Ice, along with the smaller blade Widow's Wail. It has black and red ripples through the steel. It was originally given to Jaime Lannister by his father Tywin Lannister, but Jaime gifted it to Brienne of Tarth before she begins her search for Sansa and Arya Stark.

This is the Valyrian blade of house Drumm. It was forged before "The Doom". It is currently wielded by Lord Dunstan Drumm. The sword could possibly have been the ancestral sword of House Reyne of Castamere.

Also originally Eddard Stark's sword Ice which was made out of Valyrian Steel. It was then melted down by Tywin Lannister and given to Joffrey Baratheon on his wedding day. It was named Widow's Wail by Joffrey as he claims "It will make many a widow, too". In the books it was described to have waves of colors, "waves of night and blood upon some steely shore".

This is the blade of House Dayne. it is not Valyrian but is carved from a meteorite. It carries a few of the same properties of Valyrian steel. Dawn was wielded by the famous Ser Arthur Dayne of the Kingsguard.

This is the sword of Azor Ahai a legendary hero who is prophesied to fight and defeat the Great Other. Lightbringer is thought to be a sword of living fire, also known as the Red Sword of Heroes.

The sword forged for Stannis Baratheon out of the fires of the wooden statues of the Seven through the help of Melisandre on Dragonstone is thought to be Lightbringer as it shines a brilliant light when drawn.
